Description

Parotid gland tumor grasping instrument

Technical Field

The utility model relates to the field of medical equipment, concretely relates to parotid gland tumour grabs and grabs apparatus.

Background

Parotid gland tumors are a common disease in humans, and surgical resection is the primary method of treatment for parotid gland tumors (particularly benign tumors). However, how to effectively grasp the parotid gland tumor is an important problem in the process of tumor resection surgery, which affects the efficiency and quality of the parotid gland tumor resection surgery and even determines the success or failure of parotid gland tumor treatment. The problems of tearing of tumor envelopes and pollution of tumor cell masses to an operation area occur clinically due to improper grasping, and further tumor implantation and tumor recurrence after an operation can be caused to result in failure of tumor treatment.

The existing common methods for tumor grasping in parotid gland tumor surgical operation include: clamping peritumoral tissue: the normal tissue outside the parotid gland tumor and adhered to the parotid gland tumor is clamped by hemostatic forceps or Alice forceps, and the parotid gland tumor is dragged by the adhesion of the normal tissue and the parotid gland tumor, so that the parotid gland tumor is grasped and removed. (II) pinching tumor tissue: after a part of the parotid gland tumor is stripped and exposed, a doctor holds the parotid gland tumor with fingers directly and then pinches, pulls and removes the parotid gland tumor. However, both peritumoral tissue clamping and tumor tissue pinching are very significant drawbacks. First, the peritumoral tissue clamping method requires the operator to remove the parotid tumor by removing the normal peritumoral tissue with different thickness to grasp the parotid tumor. To effectively and safely grasp a tumor, surgery often requires sacrificing much of the normal tissue for multi-point clamping. In addition, the tearing of tissues around the parotid gland tumor is inevitable during the holding process of the parotid gland tumor, and the envelope of the parotid gland tumor is also inevitable to be torn, so that the parotid gland tumor is broken. The finger pinch of tumor tissue requires that the tumor be shallow in location, of appropriate size, and sufficiently exposed. If the parotid tumor is located deep, too large, too small, or under-exposed, grasping the parotid tumor is difficult, if not impossible at all. In addition, if the fingers of the doctor are thick and large, the space of the operation area is occupied, and the operation is also influenced; due to the difficulty in controlling the operation strength, the parotid gland tumor is inevitably crushed. In summary, both the peritumoral clamping method and the tumor pinching method require great care for the operator, once the parotid tumor is ruptured, the surface of the operation wound must be immediately washed with a large amount of normal saline, the ruptured tumor body area is covered with gauze, and the edges are sutured so as to reduce the implantation recurrence of the parotid tumor cells as much as possible.

Firstly, the pulling force control difficulty of the forceps used in the forceps holding peritumoral tissue method is high, and medical staff needs to be trained for a long time, so that the staff cost is high; secondly, as the parotid gland tumor is positioned on a pair of large salivary glands in the front lower part of the ear of the human body, the parotid gland catheter is arranged at the second upper molar part of the upper jaw, the opening is positioned on the buccal mucosa at the two sides of the oral cavity, the position of the parotid gland tumor positioned on the human body is very special, and the existing clamping instrument cannot carry out 'bottom-copying' clamping from the lower part of the parotid gland tumor, so that the parotid gland tumor is difficult to grasp and operate, and the excision effect and quality are poor. For example, the two hemostatic forceps heads designed to be two sheets can generate increased pressure after passing through the joints, the circular ring design at the tail end of each hemostatic forceps is not beneficial to the grasping of the whole palm, the labor intensity can be increased due to long-time muscle fatigue, the hemostatic forceps heads are difficult to conform to the contour of tumors in salivary glands and extend into the bottoms of parotid tumor, and moreover, the slight change of the holding power can generate huge change at the tip of the forceps heads to cause the rupture of the outer membranes of the tumor. In summary, the existing clamping apparatus or method has the problems of poor excision effect and quality, difficult instrument grasping operation and the like caused by incapability of satisfying the requirement of humanized grasping of a special human body structure, namely, a parotid gland tumor.
